QtWebEngine

@Unicode this way works! thank you!

Hi @Coder-Nomad ,

two things to check:

Is find_package(Qt6 REQUIRED COMPONENTS Core Gui WebEngineWidgets) in your CMakeLists.txt? Did you even install QtWebEngine? I think it is an optional module that may not be installed by default

Regards

You were right, I had to install QtWebEngine, so that I could see this html2pdf from the example projects,

This was reported and now fixed:
https://bugreports.qt.io/browse/QTBUG-119564

This is an answer of @ekhumoro from StackOverflow:

QTBUG-42182 is quite old, but the last comment there states: "The current status in Qt 5.5 is this: WebGL and accelerated Canvas work with OpenGL and are blacklisted unfortunately for ANGLE and software renderers due to thread synchronization issues with the former and performance issues with the latter.". This would seem to match your setup, but it's unclear whether it affects Qt6 or only applies to Qt5. Another issue is that none of the WebGL tests you did seems able to identify your GPU at all, which doesn't look promising...

qwebchannel.js, where can i download it

In that very same article that you linked there is a link to the example project repository, in which you can find a copy of that file.

It was also possible to download it directly from official examples, but they moved stuff around on their website, and that URL is broken now.

@Erdium I wrote what line you have that is wrong and what it should read.

@Will-Stokes Welcome, and thanks again for sharing your findings!

@SGaist Nothing needs fixing here. The OP's entitlements weren't enough; Will found the correct entitlements that macdeployqt uses.

i found the problem since direct3d11 support with qt6.51。the direct3d11 make render good on some computer。but on some computer will cause the problem。
